Description

Technical Field

[0001] The utility model relates to the technical field of MR devices, in particular to an intelligent MR head-mounted device capable of intelligently adjusting according to head circumference. Background Art

[0002] An MR device is a device that mixes the real world and the virtual world to generate a new visual environment, which contains both physical entities and virtual information and must be "real-time". The MR device presents virtual scene information in the real scene, builds an interactive feedback information loop between the real world, the virtual world and the user, and improves the user experience.

[0003] Most head-mounted MR devices on the market mainly include two parts: a head-mounted part and a host. The head-mounted part functions to fix the product to the human head. To ensure the stable assembly of the host and meet the assembly requirements of the accessory earphones, the existing head-mounted part generally consists of a head-mounted main body made of hard materials. When worn, the head-mounted main body is located in the forehead area, and soft material straps are provided at the rear sides of both ends to wrap around the back of the head for fixation. However, the head sizes and shapes of different users are different. The obvious difference is that the head circumference affects the tightness of the strap after wearing. Since the front head-mounted main body is a fixed structure and cannot be adjusted appropriately, the larger the head circumference, the greater the passive stretching deformation of the strap, and the tighter the binding feeling on the head, which will greatly affect the normal experience of the user. Moreover, the strap is prone to structural relaxation after long-term high-load extension use, which greatly shortens the service life of the strap. For most products on the market, the head-mounted part made of hard materials can be adjusted in size to adapt to different users. Summary of the Utility Model

[0004] The utility model provides an intelligent MR head-mounted device, which is beneficial to solving the problem that the existing head-mounted main body structure is fixed and cannot be adjusted appropriately according to the head circumference of the actual user, thereby increasing the working burden of the strap structure and affecting the use experience.

[0005] The utility model is implemented as follows:

[0006] An intelligent MR head-mounted device, comprising a main body, with a head-mounted main body connected to the rear side of the main body. The left and right sides of the head-mounted main body are provided with sliding components capable of moving back and forth. The rear ends of the sliding components are connected with extension components made of rigid materials, and the rear ends of the left and right extension components are connected by a belt body made of soft materials. Among them, the sliding component includes a fixing member with a longitudinal cross-sectional profile of a "C" structure. A first moving slot is arranged inside the fixing member, and two moving members are symmetrically arranged on the upper and lower sides inside the first moving slot. A first spring arranged longitudinally is provided between the moving member and the fixing member. An insertion gap facing horizontally forward and backward is formed on the adjacent sides of the moving member. In the free state, the two moving members can approach each other within a threshold stroke. A slider is movably inserted into the insertion gap, and a controllable lateral limiting structure is formed between the slider and the moving member. The rear end of the long side direction of the slider extends to the outside of the fixing member and is connected to the extension component.

[0007] Based on the above technical solution, a number of serrated flanges are arranged on the longitudinally adjacent sides of the moving member, and a clamping groove is formed between adjacent flanges; a clamping block adapted to the clamping groove is arranged at the front end of the long side direction of the slider near the upper and lower moving members. The clamping block and the clamping groove constitute the lateral limiting structure, and the sliding direction of the slider in the insertion gap is a low-resistance sliding direction from front to back.

[0008] Based on the above technical solution, a second spring is provided between the inner end of the short side direction of the slider and the inner side wall of the fixing member. The longitudinal cross-sectional profile of the moving member is an "L" structure. A second moving slot is formed at the inner end of the short side direction of the moving member. Pressing the slider inward can compress the second spring, and the whole slider can enter the second moving slot. In this state, the clamping block is in contact with the clamping groove for limiting and restraining.

[0009] Based on the above technical solution, a support plate is provided between the second spring and the slider, and the support plate is in slidable contact with the slider.

[0010] Based on the above technical solution, the belt body includes an inner layer, a middle layer, and an outer layer arranged in sequence. A number of elastic rubber bands arranged along the long side direction of the belt body are provided inside the middle layer.

[0011] Based on the above technical solution, the elastic rubber band is composed of a number of elastic rib strips with different diameters arranged alternately.

[0012] Based on the above technical solution, a number of sheet-like middle layers are distributed at intervals along the upper side direction of the belt body, and adjacent middle layers are connected in series by elastic rubber bands to form a telescopic belt structure.

[0013] Based on the above technical solution, an upper pulling belt is provided between the top of the head-mounted main body and the top of the belt body.

[0014] On the basis of the above technical solution, an arc-shaped lower pulling belt is provided at the bottom of the middle part of the belt body.

[0015] Compared with the prior art, the present utility model has at least the following advantages:

[0016] By providing sliding components on the left and right sides of the head-mounted main body, and using the sliding components as the reference structure, the extension component, i.e., the belt body, can be displaced forward and backward relative to the head-mounted main body. This forward and backward displacement can be adaptively adjusted according to the head sizes of different users, and then the telescopic burden of the belt body can be reduced by the forward and backward movement of the rigid structure. This is beneficial to solving the problem that the structure of the existing head-mounted main body is fixed and cannot be appropriately adjusted according to the actual head circumference of the user, thus increasing the working burden of the belt body structure and affecting the use experience.

[0025] To make the purposes, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model.

[0026] In the description of the present utility model, the terms "first" and "second" are only used for descriptive purposes, and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality" means two or more, unless otherwise specifically defined.

[0027] It should be noted that when an element is referred to as "fixedly provided on" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to an element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only embodiments.

[0028] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Combined with Figures 1-6 , this embodiment discloses an intelligent MR head-mounted device, including a main unit 1. The main unit 1 includes a spectacle frame, a display screen, an optical lens module, a reflector, a reflective and transmissive lens, etc., which are prior art. Their specific structures and working principles will not be elaborated herein. Those skilled in the art can select and implement from the prior art according to the actual operation situation.

[0030] In this embodiment, a head-mounted main body 2 is connected to the rear side of the host 1. When worn, the head-mounted main body 2 is placed on the forehead. Sliding members 3 capable of moving back and forth are provided on both the left and right sides of the head-mounted main body 2. Specifically, the sliding member 3 includes a fixing member 31 with a "C"-shaped longitudinal profile. The back surface of the fixing member 31 is fixedly provided on the side wall of the host 1, and the front surface is a strip-shaped opening structure.

[0031] Combining FIGS. 3 and 4, a first moving groove 311 is provided inside the fixing member 31. Two strip-shaped moving members 32 are symmetrically provided on the upper and lower sides inside the first moving groove 311. A first spring 33 arranged longitudinally is provided between the moving member 32 and the fixing member 31. A plurality of first springs 33 are distributed at intervals transversely. The fixing member 31 and the adjacent side of the moving member 32 are assembled by snap-fitting through corresponding sinking grooves. When in use, the first spring 33 can perform longitudinal expansion and contraction and will not undergo lateral displacement.

[0032] Furthermore, an insertion gap facing horizontally forward and backward is formed between the adjacent sides of the two moving members 32. In the free state, the two moving members 32 can approach each other within a threshold stroke. A horizontally arranged and strip-shaped slider 34 is movably inserted in the insertion gap. A controllable lateral limiting structure is formed between the slider 34 and the moving member 32. The rear end of the long side direction of the slider 34 extends to the outside of the fixing member 31 and is connected to an extension member 4.

[0033] Wherein, a plurality of serrated flanges 321 are provided on the longitudinally adjacent sides of the moving member 32, and a clamping groove 322 is formed between adjacent flanges 321; clamping blocks 341 adapted to the clamping groove 322 are provided at the front end of the long side direction of the slider 34 near the upper and lower two moving members 32. The clamping blocks 341 and the clamping groove 322 constitute the lateral limiting structure, and an inclined surface structure with a lower front and a higher rear is provided on the side of the flange 321 close to the insertion gap. An inclined surface structure with a higher front and a lower rear is provided on the side of the clamping block 341 close to the flange 321. Therefore, the slider 34 has a low-resistance sliding direction from front to back in the insertion gap. When in use, the slider 34 can be easily pulled backward relative to the fixing member 31 and form a snap structure at a specific position, and will not easily return forward.

[0034] Furthermore, as Figure 4As shown, a second spring 36 is provided between the inner end of the short side of the slider 34 and the inner wall of the fixing member 31. The longitudinal profile of the movable member 32 is an "L" - shaped structure, which is inverted in the installed state. The movable member 32 forms a second movable groove 323 at the inner end of its short side. Pressing the slider 34 inward can compress the second spring 36, and the whole slider 34 can enter the second movable groove 323. In this state, the locking block 341 contacts the clamping groove 322 for limit constraint. During actual use, in the free state and when the locking block 341 and the clamping groove 322 are in position matching, the second spring 36 can push the slider 34 forward by its own elastic characteristic, making the position of the slider 34 forward. The locking block 341 on the slider 34 can be embedded into the clamping groove 322 to form a clamping structure. In this state, the structural extension deformation of the sliding member 3 can be directly realized by pulling backward. When it is necessary to retract the structure to fit a smaller head circumference for use, press the slider 34 inward to make its position rearward. After releasing the limit relationship between the locking block 341 and the clamping groove 322, the front plugging gap of the slider 34 can be moved forward, and the operation is convenient and fast.

[0035] Furthermore, in order to make the movable structure more stable and reliable, a support plate 35 is provided between the second spring 36 and the slider 34. The support plate 35 covers the entire plugging gap area. The support plate 35 is in slidable contact with the slider 34, and the two can flexibly displace relative to each other in the front - rear direction, which makes the connection structure of the second spring 36 stable and reliable.

[0036] The rear end of the sliding member 3 is connected to an extension member 4 made of a hard material. The rear ends of the two left - and - right extension members 4 are connected by a belt body 5 made of a soft material. In this embodiment, the extension member 4 is made of hard plastic, and a headset 41 is detachably connected to its outer wall. Since its front - rear position is adjustable, it is convenient to match the position of the headset 41 with the ear holes, improving the wearing comfort.

[0037] Combined with Figure 5 , the belt body 5 includes an inner layer 51, a middle layer 52, and an outer layer 53 arranged in sequence. A number of elastic rubber bands 54 are provided inside the middle layer 52 along the long - side direction of the belt body 5. In this embodiment, the belt body 5 is mainly made of nylon fabric for the inner layer 51 and the outer layer 53, and the middle layer 52 is made of a composite material of sponge and non - woven fabric. The elastic rubber bands 54 are arranged in the sponge by spraying glue at intervals along the long - side direction of the elastic rubber bands 54, making it have a certain linear stretching ability.

[0038] In order to make the elastic deformation smoother during pulling and reduce the binding experience after wearing, the elastic rubber bands 54 are composed of a number of elastic strips with different diameters arranged alternately. In this embodiment, two small elastic strips are clamped between every two large elastic strips.

[0039] Further, in order to make the belt body 5 more flexible and lightweight during stretching and extension in the future, combined with Figure 6 , a number of middle layers 52 with sheet-like structures are distributed at intervals along the upper edge direction of the belt body 5, and adjacent middle layers 52 are connected in series by elastic rubber bands 54 to form a telescopic belt structure.

[0040] In order to make the wearing more firm and reliable and not easily fall off from the top of the head, in this embodiment, an upper pulling belt 7 is provided between the top of the head-mounted main body 2 and the top of the belt body 5, and a lower pulling belt 6 with an arc-shaped structure is provided at the bottom end of the middle part of the belt body 5, which enables the head contour to be wrapped and constrained more comprehensively and tightly after wearing.

[0041] In this embodiment, by setting the sliding member 3, the deformation of its rigid structure is used to replace the telescopic deformation of part of the belt body 5, thereby reducing the working burden of the belt body 5, extending the service life of the belt body 5, making the entire wearing structure more stable and reliable, and improving the use experience.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
